Path-Q Solar

What documents should I request before accepting a solar installation proposal?

Answer

Request a complete written proposal and contract package that defines the system, expected production, price, scope, schedule, responsibilities, warranties, assumptions, exclusions, and cancellation or change terms. Do not rely on a single-page sales estimate or verbal promises.

Key points

  • Request a site-specific layout, equipment list, system size, production estimate, and key modeling assumptions.
  • Confirm total price, payment schedule, financing terms if applicable, taxes or other charges, and change-order rules.
  • Review roof, structural, electrical, permitting, inspection, utility, monitoring, and cleanup responsibilities.
  • Obtain manufacturer and workmanship warranty terms, service contacts, and any performance commitment in writing.
  • Check that ownership, access, maintenance, removal, transfer, and damage responsibilities are clear.

What it depends on

  • The proposed ownership or financing arrangement
  • Property and roof condition
  • Whether batteries, electrical upgrades, or roof work are included
  • The provider's contract and warranty structure

Risks and trade-offs

  • A low headline price may exclude necessary site work or future service.
  • Production estimates are not the same as guaranteed output unless a written commitment says so.
  • Ambiguous responsibility for roof or utility work can create delays and disputes.

Information you may need

  • Complete contract and proposal
  • Design drawings and equipment specifications
  • Production model and assumptions
  • Warranty, payment, schedule, change, and responsibility terms
